Application filed November 22, 1913. Serial No. 802,371.

1 '0 all whom it may concern Be it known that I, EMIL F. Srorrnn, a citizen of the United States of America, residing at Pontiac. in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Governors, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an automatic governor, especially designed for motor trucks and large vehicles operated by internal combustion engines.

To limit the speed of a motor truck, reduce the comsumption of fuel to aminimum,

operation of the working units of a motor truck isthe principal object of my invention and this is accomplished by providing a novel automatic governor that is installed in connection with the manifold intake pipe of an engine, whereby the supply of explosive mixture to the engine can be regulated to a nicety and automatically controlled.

My invention further aims to provide a simple and durable automatic governor wherein a valvular member regulates the supply of explosive mixtui" and a fan actuatedbutterfly valve is employed for defleeting. the explosive mixture'whereby the supply of the same can be regulated by the valvular member.

The invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, where- 111- Figure 1 is a side elevation of the automatic governor as applied to the manifold intake pipe of an explosive engine; Fig. 2 is a longitudinal sectional view of the gov- -ernor; Fig. 3 is a cross sectional view of thesame taken on the line II IIII of Fig. 2; Fig. 4 is a similar view'taken on the line IVIV of Fig. 2; Fig. 5 1s a detail view of a detached butterfly valved A governor in accordance with this inven tion comprises a tubular 0 hollow cylindrical casing 1 having the on s thereof flanged, as at 2 and provided with diametrically opposed apertured ears 3 which permit of the ends of the casing being secured in alinement with the ends of a manifold intake pipe -1 connecting the cylinders of an engine 5 with a carburetor 6. t

The casing 1 has the outer side thereof, adjacent to one end, provided with a longi trdinal enlargement 7 having a by-path 8 formed therein with the ends of the by-path in communication with openings 9 and 10 in the wall of the casing 1. The communicat-ion between the by-path S and the opening 10 is controlled by a screw valve 11 adjustablv mounted in a connection 12 formed integral with the enlargement 7 and the casing 1, said connection extending at right angles to said casing and having the outer end thereof flanged, as at 13. The screw valve 11 has a head 14: provided with apertures 15. The flange 13 of the connection 12 has an aperture 16 and the apertures 15 and 16 accommodate 'a seal 17 or other type of lock for securing the screw valve 11 in adjusted position. The seal or locking device 17 prevents the valve from being tampered with after having been set to regulate the passage of an explosive mixture through the by-path 8 and it is through the medium of the valve 11 that the speed limit of a motor truck is setand maintained, as will hereinafter more fully appear.v

The casing 1. intermediate the ends thereof, has diametrically opposed bosses 1S and 19, the boss 18 having the outer end thereof closed and the inner end provided with a bearing 20. The boss 19 has a longitudinal opening 21 cooperating with the bearing 20 in supporting the ends of a rock-shaft 22, said shaft being placed transversely of the casing 1 by inserting the same through the opening 21. The outer end of the opening 21 is closed by a detachable cap 23 screwed or otherwise mounted upon the outer end of the boss 19. The rock-shaft 22 has a flattened portion 24 and secured to the flattened port-ion by a screw 2:") or other fastening means is abutterfiy valve 26. The valve 26 is oval in plan and when diagonally disposed within the casing 1 the edges of said valve engage the walls of said casing and provide a partition adapted to deflect an explosive mixture into the opening 10 and the by-path S.

An end of the casing 1 has a spider or cross-bar 27- supporting .an inwardly projecting longitudinal stud shaft 28, and revolubly mounted" upon the said shaft is the hub 29 of a bladed wheel or fan 30. The hub 29 can slide longitudinally of the shaft 28 and the inner end of said hub is adapted to contact with a vane or lug 31, carried by the butterfly valve 26.

In operation, the HQIIIIHIPOSI'UOII of the bladed wheel or fan 30 is in proximity to the spider 27 and with a normal pressure or supm ns-i ply of explosive mixture passing through the casing 1 from the spider end thereof, the

wheel or fan 30 simply revolves without shifting longitudinally of the shaft 28. This is accomplished by the governor being used in a vertical position, as shown in Fig. 1 and the fan 30 remains at the bottom of the shaft 28 by gravity, but an excessive supply of explosive mixture causes the fan to revolve and gradually rise upon the shaft to impinge the vane or lug 31 of'the butterflyvalve 26. The vane or lug 31holds the butter-fly valve 26 open whereby the explosive mixture can pass through the casing. Now, should there be an excessive supply of explosive mixture the wheel or fan 30 is shifted longitudinally of the shaft 28 toward the.

butterfly-valve 26. The hub of the wheel or fan 30 contacts with the vane or lug 31 of the butterfly valve 26 and closes said valve, thereby shutting ofl the communication between the ends of the casing 1, except through the medium of the by-path 8. It is therefore necessary for the explosive mixture to pass through the by-path and its passage is regulated by the valve 11, which can be set to hold in check an excessive supply of explosive mixture, until the supply has become normal. For instance, when the driver of a motor truck knows that the engine operates at a thousand revolutions per minute, he can holdthe butterfly-valve 26 closed and then regulate the valve 11 whereby suflicient mixture will pass through the by-path 8 to operate the engineiat a thousand revolutions per minute. Then with the butterfly valve released the supply of ex plosive mixture can pass right through the casing 1, but should there be an excessive supply, the butterfly valve 26 is closed and the supply held in check on account of its passage through the by-path 8 being restricted by the valve 11.

From the fore-going it will be observed that my automatic governor is characterized by a fan actuated butterfly valve which deflects the mixture into a path Where its passpeed of a motor truck or similar vehicle.

While in the drawing there is illustrated a preferred embodiment of my invention, it

is to be understood that the structural elements are susceptible to such changes, as in the size, proportion and mannerof assemblage, as fall Within the scope of the appended claims.
